Self dependent task

Mon, 26 Jan 2026 18:19:17 GMT

Hi all,

I have set up a task in QMC to run after every 1 hour. Now, there are few scenarios where the task will take more than 1 hour to execute. In this case, is there any way to make it dependent on itself as well as scheduled to run after every 1 hour?

We just wanted to ensure, task does not overlap with itself and go into forever running state.

Thanks in advance.

Regards,

Sakie

By default the same task would not trigger the task unless the previous scheduled task is over.

Hi Tresesco,

The task in QMC is actually running a batch file which executes macro to create PDF reports and we have faced situation when the task is going into forever running state( and can't be aborted).

Is there any way by which we can schedule a task to run whenever it gets completed? Like any other services which runs continuously.

I am not sure, did not try any self dependent task, but did you try using On Event from Another Task in trigger scheduler on QMC?Like :

Hi Andre,

Which version of QlikView Publisher are you using? I couldn't find these many features in my QMC.

Hi Nagaraju,

I have tried this, but same named task does not appear in the drop down list. So, I believe it is not possible to make it self dependent.

Now, my only option is to make it run continuously. But I couldn't find this feature in QMC, may be because of the older version I am using.

You want to schedule task from dependency files or what? Because, Your intend seems that. Would you elaborate more. As i understand, You previous file running time Like 12:00 PM (This file assume - 1bc.qvw) then you want to schedule another qvw like 2bc.qvw - This time should be 01:00 PM

So, I recommend you to create Task Schedular like this

Go to Scheduler file

Then use this

When Running '1bc.qvw' THEN '2bc.qvw'

For this 2bc.qvw schedule time around like above from Reload Tab

Hope This Helps, If you are thinking this parts

Hi Anil,

I have a qvw which I initially scheduled to run after every 1 hour, later I have found that sometimes it is taking more than 1 hour and sometimes a few minutes to run depending upon the data size which varies from time to time.

So, we have decided to make it run after every 1 hour and if the task is still running then skip it for that hour. But I think it is not possible to make it self dependent.

Thus we are left with only option to make it run continuously, but I think this feature is not available in SR6. Is there anyway to implement this without upgradation?

Sakir

I would highly recommend to new version,

This situation, We can make without dependent from Release 6. I mean to say, just create to schedule 1 for 12:00 PM another another file 01:00 PM then it doesn't effect the existing reload.
